Ubuntu – Ubuntu 16.04 Complicated Interface Names

16.04grub2interfacesysfssystemd

I'm trying to figure out how to restore the simple interface names in Ubuntu 16.04. I.e. enp3s0 renamed to eth0.

I have tried to modify the GRUB configuration. I have tried editing /etc/udev/rules.d/10-network.rules, but both methods did nothing for me.
Help is greatly appreciated.

/etc/udev/rules.d/10-network.rules: (I hid the mac address names.)
```
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="XX:XX:XX:XX:XX:XX″,KERNEL=="enp0s0″, NAME="eth0″
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="XX:XX:XX:XX:XX:XX″,KERNEL=="wlx02c5c1866772″, NAME="wlan0″
```
And I changed this line in the GRUB configuration (/etc/default/grub) …
```
GRUB_CMDLINE_LINUX=""
```
to look like this:
```
GRUB_CMDLINE_LINUX="net.ifnames=1"
```

Tested on VBox with Ubuntu 16.04, enp0s3 → eth0

Option 1:

Override udev rule

sudo ln -s /dev/null /etc/udev/rules.d/80-net-setup-link.rules

Update RAMDisk
```
sudo update-initramfs -u
```

Option 2:

Create a systemd link file

sudo vim /etc/systemd/network/10-eth.link

Let's define name related to MAC: (There are many options, see the linked reference)
```
[Match]
MACAddress=08:00:27:de:dd:4c

[Link]
Name=eth0
```
Update RAMDisk
```
sudo update-initramfs -u
```

Option 3:

Add net.ifnames=0 to boot parameters

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash net.ifnames=0"

Update grub
```
sudo update-grub
```
